A Constructive Algebraic Hierarchy in Coq
We describe a framework of algebraic structures in the proof assistant Coq. We have developed this framework as part of the FTA project in Nijmegen, in which a constructive proof ...

Algebraic Constructions of Space-Frequency Codes
— Recently an algebraic construction of (nt × Q) space-frequency (SF) codes over finite field Fq was proposed for use in MIMO-OFDM systems, where nt is the number of transmit ...

An Algebraic Approach to M-band Wavelets Construction
This paper presents an algebraic approach to construct Mband orthogonal wavelet bases. A system of constraint equations is obtained for M-band orthonormal filters, and then a solu...

Constructing language processors with algebra combinators
Modular Monadic Semantics (MMS) is a well-known mechanism for structuring modular denotational semantic definitions for programming languages. The principal attraction of MMS is ...
